Hi, all
[Incident]
'()' appears twice in trigger's when clause.
[scenario 1]
The step is as follow:
1) The SQL to create the trigger is as follows.
---------------------------------------------
CREATE TRIGGER trigger1
BEFORE UPDATE
ON public.tab1
FOR EACH ROW
WHEN (new.a IS NOT NULL)
EXECUTE PROCEDURE public.func();
---------------------------------------------
2) Right click trigger1
3) Click CREATE Script
The SQL shown in 'Query Editor' is as follows.
---------------------------------------------
CREATE TRIGGER trigger1
BEFORE UPDATE
ON public.tab1
FOR EACH ROW
WHEN ((new.a IS NOT NULL)) # () appears twice.
EXECUTE PROCEDURE public.func();
------------------------------------------------
[scenario 2]
1) Right click trigger1
2) Click Properties...
3) Click Event tab
The SQL shown in 'When' is as follows.
((new.a IS NOT NULL)) # () appears twice.
[The detail of cause]
pg_get_triggerdef(trigger_oid, pretty_bool) get CREATE [ CONSTRAINT ] TRIGGER command for trigger
Parameter true missing in pg_get_triggerdef function.
SELECT t.oid,t.tgname AS name, t.xmin, t.tgenabled AS is_enable_trigger, t.*, relname, CASE WHEN relkind = 'r' THEN TRUE ELSE FALSE END AS parentistable,
nspname, des.description, l.lanname, p.prosrc, p.proname AS tfunction,
COALESCE(substring(pg_get_triggerdef(t.oid), 'WHEN (.*) EXECUTE (PROCEDURE|FUNCTION)'),
substring(pg_get_triggerdef(t.oid), 'WHEN (.*) \$trigger')) AS whenclause,
pgadmin4\web\pgadmin\browser\server_groups\servers\databases\schemas\tables\templates\triggers\sql\pg\10_plus\properties.sql
[The summary of correction]
pg_get_triggerdef(t.oid) => pg_get_triggerdef(t.oid, true)
Here is a patch for trigger's when clause.
Please review.
